Embodiment 1

[0027] Such as figure 1 , a sampling device for liquid food detection, comprising six samplers 1 sequentially connected through the connector 3; The body 101 is threaded, and one side of the sampler 1 is provided with an opening 11, and the opening 11 is connected with a first liquid inlet pipe 12, and the first liquid inlet pipe 12 is inclined upward, and its axial direction is the same as that of the sampler 1. The included angle of the direction is 85°, and the end of the first liquid inlet pipe 12 is connected with the second liquid inlet pipe 2 whose axial direction is the same as that of the sampler 1; the second liquid inlet pipe 2 is provided with a sliding piston Assembly, the piston assembly includes an upper piston 21, a lower piston 22, and a connecting rod 23 connected between the upper piston 21 and the lower piston 22; a traction structure 24 is connected between two adjacent piston assemblies.

[0028] Such as figure 2 , the connector 3 includes a pipe sleev...

Embodiment 2

[0031] Implement 2, differ from embodiment 1 in that; as image 3 ;

[0032] The sampler 1 is provided with two openings 11, and the axial directions of the two openings 11 are the same; and the central axes of the two first liquid inlet pipes 12 located on the same sampler 1 are coplanar; the first liquid inlet pipes 12 are inclined upward, and The included angle with the axial direction of the sampler 1 is 85°; through two openings 11, and two liquid inlet structures composed of the first liquid inlet pipe 12 and the second liquid inlet pipe 2, it is convenient to discharge the sample while sampling Air inside device 1.

Embodiment 3

[0033] Embodiment 3, on the basis of Embodiment 1 and 2, carry out in order to facilitate the control of the overall sampling, and facilitate the manipulation of the sampling device;

[0034] Such as Figure 7 with 8 A handle 4 is connected and arranged on a sampler 1 located at the top, and the handle 4 includes a handle bar 41 of U-shaped structure. A set of fixed sleeves 43 arranged on the outer peripheral side of the sampler 1 is connected between them; the handle 4 is also provided with a lifting mechanism 5 including two elastic telescopic structures 44, a cross bar 45 and a control component 46;

[0035] The pulling mechanism 5 is provided with a movable rod 47 connected to the traction structure 24 on the top sampler 1 and controlling the piston assembly to move upward along the length direction of the second liquid inlet pipe 2; two elastic telescopic structures 44 are respectively provided On the upper surfaces of the two connecting plates 42; the cross bar 45 is a...

Abstract

The invention discloses a sampling device for liquid food detection, and relates to the technical field of food detection. The device comprises at least two samplers which are connected in sequence, the sampler is provided with at least one opening, the opening is communicated with a first liquid inlet pipe, and the end part of the first liquid inlet pipe is connected with a second liquid inlet pipe of which the axial direction is the same as that of the sampler; a piston assembly is arranged in the second liquid inlet pipe in a sliding mode and comprises an upper piston, a lower piston and a connecting rod connected between the upper piston and the lower piston. A traction structure is connected between every two adjacent piston assemblies. The multiple samplers are arranged, sample injection is controlled by controlling the piston assembly in the second liquid inlet pipe to move up and down, and sampling operation of liquid in multiple different depth positions is completed in one operation.

Description

technical field [0001] The invention belongs to the technical field of food detection, in particular to a sampling device for liquid food detection. Background technique [0002] In food safety testing, it is often necessary to sample liquid food such as edible oil or beverages. The traditional sampling method is generally to use a sampling spoon or a cup-type liquid sampler to sample, that is, to use a sampling spoon to sample on the surface of the liquid or to After the sampling cup is closed, probe into the liquid and open the mouth of the sampling cup to take samples. The disadvantages of these two methods are: sampling with a sampling spoon can only take samples on the surface of the liquid, and the representativeness of the samples is not high. Since food sampling requires multi-point sampling, Therefore, the sampling method of the sampling cup needs to be sampled multiple times and then the multiple samples after sampling are mixed for analysis. The food to be sampled...
